Abstract
A glide, preferably self retaining, for the lower end of each rear leg of a walker. The device substantially reduces forward drag or resistance to walker sliding movement over a support substrate such as carpet, hard floors, concrete, ground and like, while simultaneously increasing resistance to side ways or lateral slippage. The device includes a stationary or fixed member which engages with and receives support from each walker leg lower end and includes a support shaft orientated at an acute angle of preferably about fifteen degrees (15.degree.) to the central axis of the leg. A ground engaging member is held on the support shaft for rotation only and has a lower exterior contoured ground engaging surface which, in combination with the acute angle, makes contact with the support substrate laterally from the central axis of the leg.
